[PATCH v4 0/9] (kexec-tools) arm64: add kdump support

[AKASHI Takahiro]

My kernel patches of kdump suport on arm64 are currently under reviews.

This patchset is synced with them (v27 [1]) and provides necessary changes
for kexec-tools. It can be applied on top of kexec-tools master branch.

[1] T.B.D.

Changes for v4:
 - rebased on the master branch (including Geoff's v6)
 - revive "linux,usable-memory-range" DT property (from v2), dropping
   use of "reserved-memory" nodes introduced in v3 (patch #8)
 - extend the semantics of kexec_iomem_for_each_line() per Pratyush
   (patch #1)

Changes for v3:
 - rebased on Geoff's v5
 - fix a value of estimated PHYS_OFFSET
 - add a kernel code/data segment because they now reside out of linear
   mapping due to KASLR introduction
 - remove "linux,usable-memory-range" dependency, instead using
   "reserved-memory" node
 - add -mem-min/-mem-max support

Changes for v2:
 - trim a temoprary buffer in setup_2nd_dtb()
 - add patch#6("kexec: generalize and rename get_kernel_stext_sym()")
 - update patch#7 from Pratyush
   (re-worked by akashi)
